Tecnate TMN 2526

Tecnate TMN 2526 (formerly PAT E3090) prepolymer for molding components
in the 88 Shore A hardness range when cured with 1,4-butane diol. Elastomers made from
Technate TMN 2526 have excellent low temperature properties, high abrasion resistance,
outstanding hydrolytic stability and high resilience. Technate TMN 2526 is a MDI-terminated
prepolymer based on a polyether polyol. The material can be cured with a variety of materials
to yield various hardnesses.
